DETAILED DESCRIPTION

FIG. 1 illustrates a system 100 configured to facilitate asynchronous secured point-to-point communications between a first user and a second user, in accordance with one or more implementations. In some implementations, the asynchronous secured point-to-point communications may be used to support file sharing, streaming services (e.g., voice-over-IP), and/or other communications (including but not limited to communications and/or sessions supported by Session Initiation Protocol (SIP)). By way of non-limiting example, system 100 may be used for facilitating asynchronous discovery and exchange of device identifiers (also referred to as device ID or hardware identifier), folder identifiers, and/or other information pertinent to asynchronous secured point-to-point communications.

By way of non-limiting example, at a high level, particular communications between a first user (using a first client computing platform 104 a) and a second user (using a second client computing platform 104 b) may be initiated by the first user transferring a request (e.g., a communication request) to an authentication and authorization platform 105, which may internally queue requests. Through out-of-band communication (e.g., via email), the second user is notified that some communication is available or in the process of being established. Subsequently, the second user may transfer a request (e.g., a status check request) to authentication and authorization platform 105, to check whether any requests are queued for the second user. If so, subsequently, the second user may transfer another request (e.g., a transfer request) to authentication and authorization platform 105, to indicate and/or confirm a willingness and/or readiness to participate in a particular request queued by authentication and authorization platform 105. Next, the first user may transfer a request (e.g., a status request) to authentication and authorization platform 105, to check whether the second user has indicated and/or confirmed a willingness and/or readiness to participate in the original communication request. Up to this point, each of first client computing platform 104 a and second client computing platform 104 b have only communicated with authentication and authorization platform 105, and not through a point-to-point communication with each other. At this point, first client computing platform 104 a and second client computing platform 104 b may establish a connection (e.g., a point-to-point connection) for the communication as originally requested (e.g., sharing one or more files), which may use a Session Initiation Protocol (SIP) Proxy (and/or discovery or relay servers). In some implementations, each of first client computing platform 104 a and second client computing platform 104 b may internally manage a queue of requests to control one or more asynchronous secured point-to-point communications. For example, first client computing platform 104 a may manage a first queue and second client computing platform 104 b may manage a second queue. In some implementations, an asynchronous secured point-to-point communication may be facilitated without requiring centralized storage. That is, the information to be shared will not need to be (temporarily) stored by authentication and authorization platform 105 or any other server used in the asynchronous secured point-to-point communication. In particular, even if the service and/or communication between first client computing platform 104 a and second client computing platform 104 b pertains to file sharing, these folders and/or files will not need to be (temporarily) stored anywhere besides first client computing platform 104 a and second client computing platform 104 b. In other words, centralized storage is not required for these asynchronous secured point-to-point communications. Individual requests received by authentication and authorization platform 105 are responded to individually, preferably through a response that includes a standard HyperText Transfer Protocol (HTTP) status code.

In some implementations, system 100 may include one or more authentication and authorization platforms 105, one or more client computing platforms 104, one or more servers 102, electronic storage 130, one or more processors 132, one or more user interfaces 125, external resources 138, and/or other components. Authentication and authorization platforms 105 and server(s) 102 may be configured to communicate with one or more client computing platforms 104 according to a client/server architecture and/or other architectures. Client computing platform(s) 104 may be configured to communicate with other client computing platforms via server(s) 102 and/or according to a peer-to-peer architecture and/or other architectures. Users 127 may access system 100 via client computing platform(s) 104. In some implementations, individual ones of users 127 may be associated with individual client computing platforms 104. For example, a first user may be associated with first client computing platform 104 a, a second user may be associated with second client computing platform 104 b, and so forth. In some implementations, individual user interfaces 125 may be associated with individual client computing platforms 104. For example, a first user interface 125 may be associated with first client computing platform 104 a, a second user interface 125 may be associated with second client computing platform 104 b, and so forth.

Server(s) 102 may be configured by machine-readable instructions 106. Machine-readable instructions 106 may include one or more instruction components. The instruction components may include computer program components. The instruction components may include one or more of a storage component 108, a request component 110, a status component 112, a confirmation component 114, a connection component 116, a response component 118, a communication component 120, a login component 122, an interface component 124, a service component 126, and/or other instruction components. Electronic storage 130 a may be similar to electronic storage 130, though included in client computing platforms 104. In some implementations, client computing platform 104 a may include electronic storage 130 a, in particular non-centralized storage that is local to client computing platform 104 a. In some implementations, client computing platform 104 b may include electronic storage 130 a, in particular non-centralized storage that is local to client computing platform 104 b. Processors 132 a may be similar to processors 132, though included in client computing platforms 104. Machine-readable instructions 106 a may be similar to machine-readable instructions 106, though included in client computing platforms 104.

Storage component 108 may be configured to store information electronically, e.g., in electronic storage 130. In some implementations, stored information may be indexed, organized, structured, and/or otherwise searchable. For example, the stored information may include tables, databases, relational databases, and/or other types of structural data storage. In some implementations, the stored information may include user information that identifies a set of authorized users that are authorized to access and/or use one or more software-controlled applications. As used herein, the term “software-controlled application” may refer to both (i) applications that are entirely software based, including but not limited to enterprise software, peer-to-peer software, and/or other types of software applications, and (ii) applications where a software component or a software layer is used to control a hardware application, including but not limited to code signing certificates, encrypted hard drives, security-enabled equipment, and/or other hardware applications that may be controlled by software.

In some implementations, the stored information may include registered hardware information that identifies a set of registered client computing platforms that have been registered to access and/or use one or more software-controlled applications. In some implementations, the stored information may include registered key information that identifies a set of registered keys for encryption and/or decryption that have been registered to access and/or use one or more software-controlled applications. As used herein, the term “public key” may include public keys, private keys, and/or other keys used for encryption and/or decryption of information. In some implementations, the stored information may include revoked key information that identifies a set of revoked keys for encryption and/or decryption that are no longer registered to access and/or use one or more software-controlled applications. For example, in some implementations, individual ones of the set of revoked keys for encryption and/or decryption may correspond to previously-registered client computing platforms that have been reported stolen or missing. In some implementations, the stored information may include assigned permission information that identifies a set of assigned authorization credentials that have been assigned to specific users and specific client computing platforms. Individual ones of the set of authorization credentials may be associated with individual expiration dates. In some implementations, the stored information may include revoked permission information that identifies a set of revoked authorization credentials that are no longer assigned for access and/or use of one or more software-controlled applications. In some implementations, the stored information may include available permission information that identifies a set of available authorization credentials that are available to be assigned to a specific user and a specific client computing platform.

In some implementations, the stored information may include permission information regarding authorization credential pools. For example, a particular pool or set or number of authorization credentials may be designated for a particular group of users. As long as the particular pool is not exhausted and/or otherwise fully assigned to group members, another user from the group may automatically be authenticated and/or authorized by system 100 such that an available authorization credential is assigned to this user.

In some implementations, the stored information may include at least a predetermined number of the following different types of information: (i) registered key information, (ii) revoked key information, (iii) user information that identifies a set of authorized users, (iv) registered hardware information, (v) assigned permission information, (vi) revoked permission information, and/or other information. In some implementations, the predetermined number may be 1, 2, 3, 4, and/or another number.

Request component 110 may be configured to receive requests from users 127. The requests may include communication requests, login requests, user requests, (automated) client requests, and/or other requests. In some implementations, a communication request from a particular user may include one or more of a machine identifier associated with a particular client computing platform 104 (which may be associated with the particular user), a payload identifier that identifies a payload, a recipient identifier that identifies another user (e.g., as intended recipient of the payload), a request identifier that identifies a particular communication request, and/or other information. Particular client computing platform 104 may include non-centralized storage (by way of non-limiting example, a particular NAS). Payload information may identify one or more electronic files and/or folders on this non-centralized storage. For example, a single communication request may include payload information that identifies two or more folders of electronic files on this non-centralized storage of particular client computing platform 104. In some implementations, a particular payload identifier may include a folder array identifying more than one folder as the payload of the communication request.

In some implementations, a login request may request user-specific authentication to access and/or use a particular software-controlled application. Alternatively, and/or simultaneously, in some implementations, a login request may request device-specific authorization to access and/or use a particular software-controlled application. In some implementations, individual login requests may be both user-specific and device-specific.

In some implementations, a user request may request continued access and/or use a particular software-controlled application. In some implementations, a user request may request user-specific authentication for continued access and/or use a particular software-controlled application. Alternatively, and/or simultaneously, in some implementations, a user request may request device-specific authorization for continued access and/or use a particular software-controlled application. In some implementations, individual user requests may be both user-specific and device-specific.

In some implementations, requests may include one or more of a user identifier that identifies a user, a hardware identifier that identifies a particular client computing platform 104, a machine identifier that identifies a particular public key, and/or other information. For example, in some implementations, a request may include a password that is provided by the user. For example, in some implementations, a request may include a device name that identifies a particular client computing platform 104 (e.g., that is currently being used by the user to provide the request). In some implementations, requests may include client-provided information, including but not limited to client-provided JavaScript Object Notation (JSON) Web Tokens (JWTs), client-provided expiration dates, client-provided machine identifiers, client-provided hardware identifiers, and/or other client-provided information. As used herein, the term “client-provided” may refer to information extracted by client-side software, or retrieved by client-side software, and/or otherwise provided by a client computing platform, on behalf of a user of a client computing platform, and/or by a user of a client computing platform.

In some implementations, hardware identifiers may be added to and/or provided by individual client computing platforms 104 as part of a request. For example, a hardware identifier may be a Media Access Control (MAC) address, which may be supplied and/or otherwise provided by an individual client device. In some implementations, hardware identifiers may be a machine name, or may include a machine name, or may be a combination of a MAC address and a machine name.

In some implementations, machine identifiers may identify a public key used for Public Key Infrastructure (PKI). In some implementations, a particular machine identifier may be (or include) a textual representation of a public key and/or another (generated) certificate. In some implementations, a particular machine identifier may be (or include) a textual representation of a device fingerprint or machine fingerprint. For example, the particular machine identifier may include information about the specific hardware and/or software of a particular device. In some implementations, a machine identifier may be created by hashing a certificate and/or public key. In some implementations, in response to an individual request from a particular client computing platform 104, system 100 (particularly, response component 118) may be configured to transfer an individual response to the particular client computing platform 104.

Status component 112 may be configured to receive requests and/or status-related messages from individual client computing platforms 104. For example, status component 112 may receive a status check request (also referred to as a “recipient status request” or “participant status request”) from a particular client computing platform 104 (e.g., second client computing platform 104 b). In some implementations, a status check request verifies whether authentication and authorization platform 105 has any outstanding communication requests (e.g., in its queue) that have a particular client computing platform 104 (e.g., second client computing platform 104 b) as its intended recipient. In some implementations, a status check request includes a particular machine identifier and/or other information associated with a particular client computing platform 104 (here, second client computing platform 104 b). For example, a first user may have notified a second user regarding some communication that is available or in the process of being established (here, between the first user and the second user, such as, e.g., sharing one or more folders or electronic files from the first user to the second user). In some implementations, a communication request for (peer-to-peer) file sharing may be referred to as a share request. In some implementations, status component 112 may be configured to receive certain types of requests (including but not limited to status check requests and status requests) periodically, repeatedly, and/or otherwise more than once. For example, response to receiving a response that does not indicate acceptance, second client computing platform 104 b may repeat the transfer of a status check request. For example, response to receiving a response that does not indicate acceptance, first client computing platform 104 a may repeat the transfer of a status request.

As another example, status component 112 may receive a status request (also referred to as a “sender status request” or “initiator status request”) from a particular client computing platform 104 (e.g., first client computing platform 104 a). In some implementations, a status request verifies whether authentication and authorization platform 105 has been notified by a particular client computing platform 104 (e.g., second client computing platform 104 b) to indicate and/or confirm a willingness and/or readiness to participate in a particular request queued by authentication and authorization platform 105 (e.g., through a transfer request received by confirmation component 114). In some implementations, a status request includes a particular request identifier and/or other information that identifies a particular communication request.

Confirmation component 114 may be configured to receive requests and/or request-related messages from individual client computing platforms 104. For example, confirmation component 114 may receive a transfer request (also referred to as a “confirmation request” or “participant ready request”) from a particular client computing platform 104 (e.g., second client computing platform 104 b). In some implementations, a transfer request indicates and/or confirms a willingness and/or readiness to participate in a particular request queued by authentication and authorization platform 105.

Response component 118 may be configured to transfer responses to requests, including communication requests, login requests, status check requests, status requests, transfer requests, user requests, and/or other types of requests. In some implementations, individual responses may include identifiers, including but not limited to request identifiers that identify a particular (communication) request. In some implementations, individual responses may include JWTs (e.g., provided to the user that made the request). In some implementations, individual responses may include individual standard HyperText Transfer Protocol (HTTP) status codes. In particular, responses may conform to the HTTP application layer protocol. For example, an individual standard HTTP status code may be “200”, “201”, “401”, “402”, “403”, “404”, “410”, and/or other standard HTTP status codes. For example, a “200” status code may indicate a request has been accepted. For example, a “201” status code may indicate a request has been accepted, and a new resource has been created in the process. For example, a “401” status code may indicate the request has not been accepted due to some (client) error. For example, a “402” status code may indicate the request has not been accepted due to some (client) error that requires a payment. For example, a “403” status code may indicate the request has not been accepted due to some (client) error that represents the client has no access, or no longer has access. For example, a “410” status code may indicate the request has not been accepted due to some (client) error that represents a removal or revocation of rights. In some implementations, individual responses may include or use so-called “raw sockets”. In some implementations, individual responses may conform to Quick UDP Internet Connections (QUIC). Other protocols and formats are considered within the scope of this disclosure. In some implementations, responses by response component 118 may be performed in response to (or subsequent to) one or more verifications or other actions by system 100.

For example, in some implementations, response component 118 may respond to a communication request with a “201” status code responsive to authentication and authorization platform 105 queueing a particular communication request. For example, in some implementations, response component 118 may respond to a communication request with a “200” status code (in addition to multiple machine identifiers) responsive to a particular communication request being associated with multiple client computing platforms 104 (according to authentication and authorization platform 105). Such a response may be interpreted by a client-side application (here, by first client computing platform 104 a) such that the first user can select which client computing platform 104 should be associated with (and/or added to) a particular communication request.

For example, in some implementations, response component 118 may respond to a status check request with a “200” status code (in addition to one or more request identifiers). Such a response with multiple request identifiers may be interpreted by a client-side application (here, by second client computing platform 104 b) such that the second user can select which communication request to refer to in the subsequent transfer request.

For example, in some implementations, response component 118 may respond to a transfer request with a “200” or “201” status code. Such a response may be interpreted by a client-side application and/or by authentication and authorization platform 105 that second client computing platform 104 b is willing and/or ready to participate in a particular request queued by authentication and authorization platform 105. In some implementations, the corresponding communication may be a direct point-to-point communication between first client computing platform 104 a and second client computing platform 104 b. In some implementations, the corresponding communication may be a direct point-to-point communication between first client computing platform 104 a and second client computing platform 104 b. In some implementations, through SIP Proxy services, first client computing platform 104 a and second client computing platform 104 b may use one or more relay servers to establish communications.

For example, in some implementations, response component 118 may respond to a status request with a “201” status code. Such a response may be interpreted by a client-side application (here, by first client computing platform 104 a) to indicate the second user has indicated and/or confirmed a willingness and/or readiness to participate in a particular request queued by authentication and authorization platform 105, by providing a particular transfer request for the particular communication request. In some implementations, authentication and authorization platform 105 may be configured to remove this particular communication request from its queue at this point. Alternatively, a “40x” code may be interpreted as authentication and authorization platform 105 being unable to locate the particular communication request in its queue.

Connection component 116 may be configured to securely establish a point-to-point connection between two or more client computing platforms 104 (e.g., between first client computing platform 104 a and second client computing platform 104 b). For example, connections and/or communications may be secured by cryptography, including but not limited to the use of Public Key Infrastructure (PKI). In some implementations, connection component 116 may securely establish a point-to-point connection in accordance with a particular communication request (e.g., for the communication of a particular payload between first client computing platform 104 a and second client computing platform 104 b). In some implementations, connection component 116 may establish a communication session over Internet Protocol (IP) networks in a manner supported by Session Initiation Protocol (SIP), e.g., through a SIP Proxy. As used herein, a point-to-point connection may be relayed, e.g., by a relay server. In some implementations, one or more features and/or functions attributed to connection component 116 may be implemented by service component 126.

Communication component 120 may be configured to securely communicate between two or more client computing platforms 104 (e.g., between first client computing platform 104 a and second client computing platform 104 b). In some implementations, communication component 120 may securely communicate in accordance with a particular communication request (e.g., for the point-to-point communication of a particular payload between first client computing platform 104 a and second client computing platform 104 b). In some implementations, communication component 120 may securely communicate using a point-to-point connection established by connection component 116. In some implementations, communication component 120 may communicate over Internet Protocol (IP) networks in a manner supported by Session Initiation Protocol (SIP), e.g., through a SIP Proxy. As used herein, point-to-point communication may be relayed, e.g., by a relay server. In some implementations, one or more features and/or functions attributed to communication component 120 may be implemented by service component 126.

Referring to FIG. 1 , login component 122 may be configured to receive user input (e.g., from one or more users 127) on client computing platforms 104. For example, the user input may represent a particular communication request, by a particular (first) user. Login component 122 may be configured to provide requests to authentication and authorization platform 105 (and, in particular, to request component 110). Responses from authentication and authorization platform 105 (and, in particular, from response component 118) may be provided to client computing platforms 104 (and, in particular, to login component 122). In some implementations, user input received by login component 122 may include a user identifier, a password, payload information (e.g., an array of folder identifiers), a recipient identifier (e.g., a name and/or an email address for the second user), and/or other information. In some implementations, login component 122 may be configured to add certain information to the received user input to form requests, including but not limited to a hardware identifier, a machine identifier, a (communication) request identifier, and/or other information. For example, this information may be available locally on the particular client computing platform 104. In some implementations, login component 122 may (regularly and/or at recurring intervals) automatically provide (e.g., to authentication and authorization platform 105) user requests that request continued access and/or use of the particular software-controlled application. Certain responses received from authentication and authorization platform 105 may prompt actions by client computing platforms 104, e.g., by login component 122.

Referring to FIG. 1 , interface component 124 may be configured to generate, effectuate, and/or present user interfaces 125 on client computing platforms 104 to users. For example, interface component 124 may be configured to present a particular user interface 125 on a particular client computing platform 104 to a particular user. For example, particular user interface 125 may include one or more portions or sections. The one or more portions and/or sections may include a first portion, a second portion, a third portion, a fourth portion, and so forth. In some implementations, a portion of a particular user interface 125 may enable a user to enter and/or select information and/or actions, including but not limited to a particular user identifier, a particular password, and a graphical user interface element to transfer a user request to authentication and authorization platform 105. In some implementations, a portion of particular user interface 125 may be used to present a response to the user (e.g., from response component 118). By way of non-limiting example, see FIG. 4 for an exemplary user interface 400.

Referring to FIG. 1 , service component 126 may be configured to facilitate interaction with a SIP Proxy and/or otherwise provide SIP Proxy services. For example, first client computing platform 104 a may provide an IP address during discovery (e.g., using a discovery server). For example, second client computing platform 104 b may provide a (destination) IP address during discovery (e.g., using a discovery server). By way of non-limiting example, service component 126 may implement one or more features and/or functions attributed to connection component 116, including but not limited to establishing a communication session over Internet Protocol (IP) networks in a manner supported by Session Initiation Protocol (SIP). In some implementations, service component 126 may implement one or more features and/or functions attributed to communication component 120, including but not limited to securely communicate in accordance with a particular communication request (e.g., for the point-to-point communication of a particular payload between first client computing platform 104 a and second client computing platform 104 b). In some implementations, service component 126 may provide access to open source software, including but not limited to open source software related to SIP services.

By way of non-limiting example, FIG. 3 illustrates an exemplary flow chart 300 as may be used in system 100 (in particular, by authentication and authorization platform 105). Flow chart 300 may start at Communication Request 110 a (from first client computing platform 104 a to authentication and authorization platform 105) as depicted in FIG. 3 , followed by First Response 118 a (from authentication and authorization platform 105 to first client computing platform 104 a). Subsequently, flow chart 300 may continue at Status Check Request 112 a (from second client computing platform 104 b to authentication and authorization platform 105) as depicted in FIG. 3 , followed by Second Response 118 b (from authentication and authorization platform 105 to second client computing platform 104 b). Subsequently, flow chart 300 may continue at Transfer Request 114 a (from second client computing platform 104 b to authentication and authorization platform 105) as depicted in FIG. 3 , followed by Third Response 118 c (from authentication and authorization platform 105 to second client computing platform 104 b). Subsequently, flow chart 300 may continue at Status Request 112 b (from first client computing platform 104 a to authentication and authorization platform 105) as depicted in FIG. 3 , followed by Fourth Response 118 d (from authentication and authorization platform 105 to first client computing platform 104 a). Individual responses may include individual standard HTTP status codes.

By way of non-limiting example, FIG. 4 illustrates an exemplary user interface 400 as may be present to a user on a particular client computing platform. User interface 400 may include graphical user interface elements 41 a and 41 b that are configured for a user to enter and/or select information (including but not limited to a particular authorization credential). For example, element 41 a may be used to enter a user identifier and element 41 b may be used to enter a password. User interface 400 may include an action button 42 labeled “Request Communication”. Upon selection and/or engagement of action button 42, user interface 400 may initiate and/or otherwise provide one or more requests (including a particular communication request) to authentication and authorization platform 105. For example, a first request may be a login request to a particular software-controlled application, based on the entered user identifier and password. For example, a second request may be a communication request for continued access and/or use of the particular software-controlled application that implements file sharing. User interface 400 may include graphical user interface element 41 c, labeled “Information for User”, which may be used by the system to provide information to the user, including but not limited to feedback, comments, or prompts. For example, a client-side application may interpret responses from authentication and authorization platform 105 (including but not limited to standard HTTP status codes) and provide information to the user, through graphical user interface element 41 c, that is based on the responses from authentication and authorization platform 105. User interface 400 may include graphical user interface element 41 d, labeled “Software-controlled application”, which may be used by the system to provide (continued) access to the particular software-controlled application as requested by the user.

Referring to FIG. 1 , in some implementations, authentication and authorization platform(s) 105, server(s) 102, client computing platform(s) 104, and/or external resources 138 may be operatively linked via one or more electronic communication links. For example, such electronic communication links may be established, at least in part, via one or more networks 13 such as the Internet and/or other networks. It will be appreciated that this is not intended to be limiting, and that the scope of this disclosure includes implementations in which components may be operatively linked via some other communication media.

A given client computing platform 104 may include one or more processors configured to execute computer program components. The computer program components may be configured to enable an expert or user associated with the given client computing platform 104 to interface with system 100 and/or external resources 138, and/or provide other functionality attributed herein to client computing platform(s) 104. By way of non-limiting example, the given client computing platform 104 may include one or more of a desktop computer, a laptop computer, a handheld computer, a tablet computing platform, a NetBook, a Smartphone, a gaming console, and/or other computing platforms.

In some implementations, assignment verifications may be performed by system 100 to verify whether a particular authorization credential (e.g., the authorization credential associated with a client-provided hardware identifier and a client-provided machine identifier in a particular request) corresponds to one of the authorization credentials in the set of assigned authorization credentials (e.g., as included in the stored information).

In some implementations, authorization credential-revocation verifications may be performed by system 100 to verify whether a particular authorization credential (e.g., the authorization credential associated with a client-provided hardware identifier and a client-provided machine identifier in a particular request) corresponds to one of the authorization credentials in the set of revoked authorization credentials (e.g., as may be included in the stored information). In some implementations, authorization credential-revocation verifications may be performed by system 100 to verify whether a particular authorization credential (e.g., the authorization credential associated with a client-provided hardware identifier and a client-provided machine identifier in a particular request) corresponds to one of the authorization credentials in a set of authorization credentials that are no longer assigned (or authorized) for access and/or use of a particular software-controlled application.

In some implementations, expiration verifications may be performed by system 100 to verify whether particular authorization credentials and/or JWTs have expired. In some implementations, expiration may be based on individual expiration dates that are associated with individual authorization credentials. Expiration dates may be included in the stored information.

In some implementations, authorization credential-availability verifications may be performed by system 100 to verify whether the set of available authorization credentials includes an individual available authorization credential (e.g., that is currently available, or that is available in view of certain context such as identifiers and/or other information). For example, in some implementations, an authorization credential may be available provided that it is unassigned, unrevoked, and available to be assigned to a particular user. In some implementations, availability may be determined in view of an authorization credential pool. For example, a particular group of users may use an authorization credential pool that includes a particular number of authorization credentials such that there may only be an available authorization credential if less than the number of authorization credentials in the pool is currently assigned to the group of users that use the authorization credential pool.

External resources 138 may include sources of information outside of system 100, external entities participating with system 100, and/or other resources. In some implementations, external resources 138 may include a provider of information which may be used by system 100. In some implementations, external resources 138 may include a provider of particular software-controlled applications which may be made available to users through system 100. In some implementations, some or all of the functionality attributed herein to external resources 138 may be provided by resources included in system 100.
